Ah, now it all makes sense. Looks like Google Translate got thrown by the 一元性 and chose "Hazime" for both 一 and 元. "Hajime" is a reading for both of those kanji when used as personal names. Why Google Translate would use a non-standard (outside of Japan) romanization is beyond me.

Anyhoo, I'd translate it as:

"I believe that Dr. Feldenkrais borrowed the concept of "shisei" from Japanese culture (judo) as a word illustrating somatic words (unitarity of body and mind)."
